We've only added a second show strictly for EMH guests twice, with the second one being over a month ago. Unfortunately, unless you are told otherwise by one of us parade/F! CMs, you're stuck going to the regular day guests show.
When I was there 3 weeks ago, park closing and Fantasmic was 9:00pm. I got to the park just as Fantasmic started and I got my wristband. I rode ToT walkon twice. I was going to do RnR twice next, but Fantasmic had just left out and people were pouring out. The wait for RnR was about 25 minutes. I ended up only doing it once. So if you are not seeing Fantasmic, try to get to those rides earlier.
